No source available for "uwTickPrio() at 0x20000004"

I working with a custom board with MCU STM32F105RB, When I debug using ST CUBEIDE, I get following "No source available for "uwTickPrio() at 0x20000004"  "0693W00000KZorZQAT.png

Thank You @Pavel A.​ and @Community member​ 

I am finally able to solve the problem.

Previously I used STM32F103RB- Nucleo board as the programmer/debugger. Then I change to ST-LINK V2 programmer as my programmer/debugger.

Now it's working fine.

This message is misleading. uwTickPrio is not a function. It looks like your program jumps to data memory, or thru a bad function pointer, or stack corruption occurred. Debug.

Shows none of the code involved...

Really wouldn't be code in the RAM in most cases.

Use the debugger.

Review and single step your code. Try to be understand the point of failure.

Check how it would find its way to uwTickPrio, and where and how that's used in your code.

Check vector table.

Check how SysTick or whatever timing source you're using gets initialized.
